This report aims to build on the 2015 “Cheadle Town Centre Transport Study” (Phase 1), and further assess the characteristics of the existing highway network across the town to identify the locations and routes that will be affected by the revised housing and employment land provision. Evaluation has been provided on what impacts the resultant traffic increase has had on journey times, queueing and delay within the town; and mitigation measures have been suggested, in order to remediate the adverse effects brought about by the increase in vehicular trips through the town centre. In 2015, Amey was jointly commissioned by Staffordshire County Council (SCC) and Staffordshire Moorlands District Council (SMDC) to undertake a transport study to investigate the potential impact of additional vehicular trips on the highway network around Cheadle town centre. As identified in 2015 as part of the Local Plan, approximately 1,320 new homes and approximately 8.86 hectares of additional employment land was identified as needing to be provided by 2026 across Cheadle. The “Cheadle Town Centre Transport Study” (Phase 1) identified and highlighted the negative impact caused by the new developments on the network, specifically with regard to the PM peak and on specific junctions and routes within the network. Numerous links were identified to be operating close to or at capacity during the without-development scenario. Of particular note were the A522 Tape Street and B5417 Queen Street links, where prolonged traffic queuing was modelled. Conditions on these links were further exacerbated in the post development scenario with greatly reduced spare capacity and reduced ability to successfully discharge flows The Preferred Options Sites & Boundaries future housing & employment land allocations were reconsidered following the results of the “Cheadle Town Centre Transport Study” (Phase 1). Amey were subsequently reappointed Staffordshire Moorlands District Council to produce a second transport study, building from the previous, 2015 study, which for the purposes of this report shall be called the “Cheadle Town Centre Phase 2” study.
